A system for facilitating development of information material comprises a material generation apparatus operable to generate information material and metadata describing the content of the information material and to store the information material on a data carrier and to store the metadata separately in a data store. The system includes at least one metadata node operable to process the metadata, and a data communications network for providing a facility for communicating the metadata to and from the metadata node. The data communications network and the material generation apparatus each include a wireless data communicator for providing a wireless data communications link with the material generation apparatus and the network. The wireless data communications link provides a facility for communicating the metadata to the metadata node via the network, when the generation apparatus is within range for data communications via the wireless link. Accordingly, a facility for producing information material such as a/v material is provided with an improved work flow, because metadata generated with the a/v material can be communicated systematically to an ingestion processor or the like separately via the wireless link when in range. Navigation and editing of the material is thereby facilitated.
